To all whom'z'fmdy concern Beit anaemia-arr; Davin w- Iiiiii-ire,

ac-itizen of the United States; residing Oregon City, in the county ofClack and State of O'regon', have inventedee'rtain new and usefulImproveme ts Tension Attachments" for Windin Mae fines; of which thefollowing is a specification.

The present invention relates to an im; roved tension device for windingmachines; and has for an object to provide inrproved means for varyingthe. tension tic-'- cording to. the size of yarn'which is being wound:

Another object of the invention is to provide a variable tension deviceof this character which may be easily and quickly applied to the usualtype of winding machines without changing or substituting any of theparts thereof.

Briefly stated, the invention embodies a weight, arm which may be hookedupon the usual winding machine in lieu of the ordinary weight and whichis held in position upon the machine without the use of brackets,pivots, or the like, and which is per mitted to swing or rock upon itsfulcrum for exerting the desired pressure on the yarn.

The invention further aims to provide a quick attachment for windingmachines wherein a single weight is used and wherein the weight may bequickly adjusted to exert the desired pressure, and wherein the positionof the weight may be determined ac cording to the size of yarn or thetension desired.

The above and various other objects of the invention will in partbedescribed in and in part understood from the following detaileddescription of the present preferred embodiment, the same beingillustrated in the accompanying drawing wherein Fig. 1 is a fragmentaryend elevation of a winding machine having the tension device of thisinvention applied thereto, and

Fig. 2 is a detail perspective view of the improved tension device.

Referring to the drawing, 10 designates a winding machine of ordinaryconstruction having a spindle 11 on which yarn 12 may be wound, the yarnbeing taken from a bobbin or spool 13 or other suitable source ofsupply. The machine carries a tension arm 14 having friction or tensiondiscs 15 between which the yarn 12 is drawn during Serial no. 658,974.

otejc'l" upon a horizontal od 17" a the tension ans 14'. is usually.cons of which is loop weights re selected according to the size of theyarn and the tension desired, and hung upon the hook 20.

The-present invention rovides a weight lever 21 of suitable lengtliprovided at one end with a laterally extending fork22 the arms of whichextend upwardly and are spaced apart a distance suflicient to freelyreceive therebetween the loweredge of the tension arm 14. The fork 22 ismerely placed up against the arm 14 so that the lever 21 may rock uponthe fork as a fulcrum. The arms of the forkhold the lever 21 fromlateral displacement-(Y Spaced a short distance from the fork 22is aneye 23 formed in the lever 21 for receiving .the hook 20 thereto so thatthe lever is suspended on the hook instead of the usual weight. Theouter end of the lever 21 is provided with a row of suitably spaced.apart openings 24 adapted to receive a hook -25 of a weight 26. Thehook 25 may be engaged in any one of the openings 24, and;v the openingsrepresent different tensions for the weight upon the hook 20. V

The lever 21 may be stamped; and bent from sheet metal and the weightmay be formed of any suitable materiakhaving the necessary specificgravity, such as iron so that the weight may be of .aiconvenient sizefor handling and will not" be bulky or in the way. The weight preferablyis of two ounce size because its eflective pressure may be variedaccording to its position upon;

the lever 21.

The tension device may thus be easily and economically manufactured andmay be quickly applied by merely placing the form 22 against the loweredge of the tension arm 14 and fitting the arm 23 over the hook-20. Theweight 26 is then suspended upon the lever 21 so as to exert a downwardpull on the hook 520 variable according to the position ofthe weight 26.

Various changes and modifications may be made in the details ofconstruction and design of the above specifically described em bodimentof the invention, the same being restricted only by the scope of thefollowing claims. a

What isclaimed is:

1. A tensiondevice for winding machines having the usual tension arm andweight hook, comprising a lever provided upon one end with an upwardlyextending fork for seating against the tension arm and having an eyespaced from the fork to receive said hook therein, said lever having aplurality of openings spaced longitudinally of the lever between the eyeand the free end of the lever, and a weight removably positioned in saidopenings for exerting a variable pressure upon the weight hook.

' 2. A-tensiondevice of the character described comprising a leverhaving a row of openings spaced longitudinally of the lever and having apivot eye inwardly of said openings, said lever having a lateraldisposed portion upon its inner end having upwardly extending fork armsand adapted to serve as a fulcrum upon which the lever may swing, and aweight arranged for selec tive engagement in the first mentioned openings of the lever.

3. A tension device for winding machines comprising a flat bar having afork bent laterally from its inner end and having its arms extendingupwardly for engagement about the tension arm of a winding machine, saidbar having an eye spaced from the fork to receive the weight hook of awinding machine and further having a plurality of openings spacedlongitudinally of the bar between the first mentioned opening and itsouter end, a weight, and a hook on the weight for selective engagementin the last mentioned openings. 7
